+# Robot Requirements
+
+1. If the driver presses the "Up" arrow, then the cart shall increase its speed by 1,000 furlongs per fortnight.
+2. If the driver presses the "Down" arrow, then the cart shall decrease its speed by 1,000 furlongs per fortnight.
+3. The cart shall not travel faster than 15,000 furlongs per fortnight on smooth terrain, 10,000 furlongs per fortnight on moderate terrain, and 5,000 furlongs per fortnight on rough terrain.
+4. If the driver presses the "Right" or "Left" arrow, then the cart's wheels shall deflect 5° right or left, as appropriate.
+5. The cart shall not deflect its wheels more than 30° away from "forward" in either direction.
+6. If the driver presses the "Emergency Stop" button, then the cart shall perform an emergency stop.
+7. If the cart is traveling faster than its maximum speed, then it shall decrease its speed by 1,000 furlongs per fortnight.
+8. If the short-range radar detects that the cart is overtaking a moving object, then the cart shall decrease its speed by 1,000 furlongs per fortnight.
+9. If the short-range radar detects a stationary object in the cart's path, then the cart shall perform an emergency stop.
+10. If the short-range radar detects an object in the cart's path that is approaching the cart, then the cart's wheels shall deflect 5° to avoid a collision.
+11. If no other action is required, then the cart shall display its current speed and heading.
+12. If the cart's wheels are turned too far away from "forward", then it the cart's wheels shall deflect in the direction necessary to return to tolerances.
+13. An emergency stop, whether commanded by the driver or directed by the cart's safety logic, shall override all other possible actions *except* turning to avoid a collision.
+14. If the cart cannot perform a required action, it shall display a message explaining why.
+15. If the cart's previous action was an emergency stop, and if the cart has not stopped, then the cart shall display a message explaining why.
